The material shown is good, but there are some aspect that must be reviewed.
In part 2, its not show correctly the vector character of momentum when the arrow of the balls in collision are turned 180º. This is not correct for the sum of two vectors.
In part 3 the answer of the situation when in collision the second is in rest before the collision is not correct. The correct ansewer is v1fin =0 and v2f= 2 m/s and in the question is shown that the correct answer is v2f= 1 m/s.
Please is important to show physisc in correct form.
